span error: ±0.08 % of reading.

Mounting position

Rotations in the plane of the diaphragm have a negligible

effect. A tilt from the vertical of up to 90° causes a zero

point shift of up to 0.5 kPa (5 mbar, 2 inH2O), which can be

corrected by making an appropriate zero position

adjustment. There is no effect on the measuring span.

In applications where a dynamic inclined installation is

required (e.g. naval applications with maximum vessel

inclination of +/-22.5°), the maximum error can be up to 3

mbar for 266DSH

Such error might be resulting in a deviation from the

standard accuracy with percentual magnitude depending

on the range of the selected device.

In case of non-dynamic inclined installations, this effect

can be eliminated by performing a zero calibration in the field.
